  • The lactose, total nitrogen and total lipid contents of human breast milk were determined longitudinally after protein and term deliveries. Milk samples were obtained from day 2 to 5, on weeks 1, 2, 4, and 6 after preform (PM : n = 24) and term (TM : n = 22) deliveries. The lactose contents of PM and TM increased from 5.28 g/dl and 5.93 g/dl at days 2 to 5, to 7.95 g/dl,7.87 g/dl at 6 weeks, respectively. The total nitrogen contents of PM and TM decreased significantly during the first 6 weeks after birth (from 374 to 220 mg/dl versus 382 to 220 mg/dl respectively). However the total lipid contents of the PM and TM increased during the same periods. Significant differences in the total lipid contents between the PM and TM were 2.15 versus 3.27 g/dl at 2 weeks, and 3.26 versus 2.52 g/dl at 6 weeks, respectively. The energy intakes of preform infants was 134.8 ㎉/kg/d during the 6 weeks of lactation, which satisfied with energy requirements (85-130 ㎉/kg/d) of the preform infants.

  • Erythrina stricta, a deciduous tree widely used traditionally in indigenous system of medicine for various ailments such as rheumatism, fever, leprosy, epilepsy etc. The leaves of Erythrina stricta was extracted with ethanol (70%) and used for the evaluation of various in vitro antioxidant assays which includes H - donor activity, nitric oxide scavenging, superoxide anion scavenging, reducing ability, hydroxyl radical, hydrogen peroxide scavenging, total phenolic content, total flavonoid content, total antioxidant activity by thiocyanate and phosphomolybdenum method, metal chelating, $\beta$-carotene bleaching, total peroxy radical assays. The pro-oxidant activity was measured using bleomycin-dependent DNA damage. Ex vivo models like lipid peroxidation and erythrocyte haemolysis were also used to study the antioxidant property of the extract. The various antioxidant activities were compared with suitable standard antioxidants such as ascorbic acid, butylated hydroxyl toluene, $\alpha$-tocopherol, curcumin, quercetin and Trolox. The generation of free radicals viz. $O_2^{{\cdot}-}$, $OH^{\cdot}$, $H_2O_2$, $NO^{\cdot}$ and peroxyl radicals were effectively scavenged by the ethanolic extract of Erythrina stricta. In all the methods, the extract offered strong antioxidant activity in a concentration dependent manner. The total phenolic content, flavonoid content and total antioxidant activity in Erythrina stricta were determined as microgram (g) pyrocatechol, quercetin and $\alpha$-tocopherol equivalent/mg respectively. The extract did not exhibit any prooxidant activity when compared with ascorbic acid. The results obtained in the present study clearly indicates that Erythrina stricta scavenges free radicals and reduces lipid peroxidation, ameliorating the damage imposed by oxidative stress in different disease conditions and serve as a potential source of natural antioxidant.

  • The possibility of grape seeds as industrial resources was tested by analyzing various chemical proper-ties of their oils from seven different species. The range of crude oil content of the grape seeds was 26.0-32.0% showing the highest content in Steuden, Mean individual fatty acid contents in the grape seeds were lioleic (70.75%) oleic (18.48%) stearic (2.01%) and palmitic (8.45%) acids. Stearic acid was low in Jingyu and high oleic acid was found in Fugiminori compared with other grape strains. Total lipirds were consisted of nutral lipid (87.25%) glycolipid(4.68%) and phospholipid *8.06%) Content of crude proteins was approximatery 11.2% with some variation between strains. Total sugar content was 2.35~5.63$\mu$g/mg with reducing sugar 3.20$\mu$g/mg. Mean saponification value of crude oils was 186.3mg.KOH.oil Antioxidant activity of grape seed oils was better than that of sesame oil resulting in the hi-oils and sesame oil after heat treatment at 18$0^{\circ}C$.

  • The effects of MCC and palm oil at different levels on lipid metabolism were assessed in adolescent rat. Dietary fat levels were 20% and 40% (kcal/kcal) and MCC level were 0%, 2%, and 4% (wt/wt). The experimental period took 8 weeks. During the experiment, weight gain and food efficiency ration were not affected by dietary factors. The weight of thymus however, was lower in high fat groups than in middle fat groups. The contents of total lipid and total cholesterol in plasma and HDL-cholesterol in plasma and HDL-cholesterol were significantly affected by dietary factors. The concentrations of cholesterol in LDL and VLDL , and the triglyceride content of VLDL was higher in high fat groups than in middle fat groups. Adding MCC lowered the LDL triglyceride in the high fat groups. The analysis of plasma fatty acids generally reflected the composition of the dietary palm oil. MCC had significant effects on total lipid and triglyceride of feces, but not on total cholesterol . In conclusion, the level of MCC had little hypolipodemic effects on lipid metabolism in rats fed a high fat diet. the middle fat group that contained 4% MCC showed increased contents of fecal triglyceride than the others, indicating that MCC had an effect on lipid absorption. Therefore, the other physiological functions of MCC need to be tested for their useful applications.

  • This study was conducted to investigate the effects of caffeine on lipid and mineral content in the serum of rats given a caffeine free diet(FC), a low caffeine diet(LC), a medium caffeine diet(MC), a high caffeine diet(HC) or a super-high caffeine diet(SHC) for 5 weeks. Thirty male Sprague-Dawley rats(body weight, $110{\pm}0.3$ g) were blocked into 5 groups and fed diets with or without pure caffeine. Caffeine intake models showed a lower mean-weight gain, food intake and food efficiency in the high caffeine diet groups(MC, HC and SHC groups) than the groups receiving a caffeine free or low caffeine diet(FC and LC groups). Serum total lipid, total cholesterol and LDL-cholesterol levels decreased, but the serum HDL-cholesterol level increased according to the increase in caffeine intake. Serum total lipid, HDL-cholesterol and serum triglyceride were significantly lower in the HC and SHC groups than the FC group. All of the serum minerals decreased as caffeine intake increased. Serum iron, calcium, magnesium and phosphorus significantly decreased in the HC and SHC groups compared to the FC group. Caffeine intake was associated with less weight gain and reduced serum total cholesterol, triglyceride and total lipid. The results suggest that rats fed high amounts of caffeine may be susceptible to osteoporosis due to their low levels of calcium, magnesium and phosphorus.

  • Objective : The objective of this study was to investigate the antioxidative effects of Carthami Flos extract. Methods : Total antioxidant status was examined by total antioxidant capacity(TAC) and total antioxidant response(TAR) against potent free radical reactions. The effect of Carthami Flos extract was examined far details of total phenolic content concentration at which 1,1-dipheny1-2-picrylhydrazyl(DPPH) radical scavenging activity was inhibited, the inhibitory effect on lipid peroxidation, and the effect on reactive oxygen species(ROS) generation. Results : TAC of Carthami Flos extract at the concentration of 5 mg/ml was 1.84 mM Trolox equivalent. 2. TAR of Carthami Flos extract, on the other hand, couldn't be determined due to interference from unidentified compounds. 3. Total phenolic content of Carthami Flos extract at the concentration of 5 mg/ml was 2.01 mM gallic acid equivalent. 4. Concentration of Carthami Flos extract at which DPPH radical scavenging activity was inhibited by 50% was 6.43 mg/ml as compared to 100% by Pyrogallol solution as a reference. 5. The inhibitory effect of the extract on lipid peroxidation was examined using rat liver mitochondria induced by FeS04/ascorbic acid. Carthami Flos extract at the concentration of 10 ms/ml slightly but significantly decreased TBARS concentration. The extract continued to prevent lipid peroxidation in a dose-dependent manner. 6. The effect of Carthami Flos extract on reactive oxygen species(ROS) generation was examined using a cell-free system induced by hydrogen peroxide/FeS04. Addition of 1 mg/ml of Carthami Flos extract significantly reduced dichlorofluorescein(DCF) fluorescence. Carthami Flos extract caused concentration-dependent attenuation of the increase in DCF fluorescence, indicating that the ektract significantly prevented ROS generation in vitro. Conclusion: : Antioxidant efffcts of Carffami ffor extract seem to be due, at least in part, to the prevention offree radical-induced oxidation, fellowed by inhibition of lipid peroxidation.
